Offline-First Mobile App for Port Workers – Technology Recommendation (VBCS vs Native)

We are evaluating Oracle Visual Builder Cloud Service (VBCS) for developing a mobile application for port workers used to perform inspection activities.

The application will be used in port areas where internet connectivity is unavailable or very poor. Users need to capture photos and short videos as part of inspection records. The app must function completely offline and sync data later, typically when users return to the terminal office after 4–5 hours and regain stable connectivity.

Key functional requirements include:

Offline authentication
Local storage of inspection data (including photos)
Local transaction queue (store-and-forward)
Sync status indicators for users
Retry and conflict handling during data synchronization
